Application filed April 13, 1907, Serial No. 368,056,.

To all whom it may concern:

Be it known that I, PHILIP T. DODGE, a citizen of the United States, and aresident of Washington, in the Distric'tof Columbia, have invented a newand useful Improvement in Linotype Machines, of which the following is a specification.

- My invention relates to linotype machines whereina series of magazines, each contaming a font or set of matrices, is combined with means. for selecting matrices, assembhng them in line, transferrlng the composed lines to the casting mechanism, and therei after returning1 the matrices, through a dis tributing 'm'e anism j-to the magazines. Such. a machine, containing a single magazinc, is represented for example in U. S. Letters Patent-No. 436,532.

The aim of my invention is to provide im proved means whereby the matrices may be delivered at will from one magazine or another, and this by the employment of a single series of escapements to control their release.

' In carrying my invention into effect, I

combine with a series of superposed magazines, standing normally at rest, an escape- Inent mechanism including a single series of escapements and movable vertically so that it may be brought into operative relation to any one of the ma azines in order to deliver the matrices there rom into a channel-plate through which they are directed to the assembling mechanism.

' Thema 'azines are mounted in such man.

facilitate this'removalof the magazines, 1 provide a pair of arms whereby they may be supported and suspended during their introduction and removal, and in order that these arms may be brought into operative relation to the respective magazines, Iarrangc them to be adjusted vertically; To this end they may be attached to vertical slides mounted in the main-frame, orsupported in any other.

manner which will adriiit of their being raised and lowered at will. I

Specification of Letters Patent. Patented March 31, 1908.

[-Benewed November 21, 1907. Serial at. 403,192;

In the drawings -J igure 1 is a vertical section of a machine hav ng my invention in-i corporated therein, the-lowermost of the four magazines'being in operative position. Fig. i 2 is a similar view showing the magazines retracted in OH er to permit the vertical adjustment of the escapelnent devices.

Referring to the drawings, A represents a rigid main-frame which may be of any form or construction adapted'to sustain the other 5 parts of the machine. v p

B, B, &c., represent a series of superposed inclined magazines remo'vably seated and firmly supported in a secondary frame C, mounted to slide horizontally forward and backward in the main-frame A, in order to carry the series of magazines to and from their operative ositions. This secondary framemay be 0 any suitable construction and maybe supported in the m-ain-frame'by horizontal guides or supports of any suitable character; In the drawing, I have shown it provided with supporting rollers 0, arranged to travelon horizontal tracks a.

While prefer to arrange the magazine 30 supportin framcto move in a horizontal direction ecause ofthc ease of movement,

'it will be understood that the only essential requirement is that the frame shall move in such direction as to .withdraw the magazines endwise from the escapcmcnt, and therefore the expression horizontal movement 'as used ,in this specilicatim, should be understood as including any kindred movement,

which effects the propel retraction of the magazines.

The forward and backward movement of the frame Omay bc ellccted by hand orby any suitable mechanism. In the-drawings I have shown for thepurposc eccentrics l) secured on a horizontal shaft dscated in the main-frame. The eccentrics are arranged to bear between vertical arms c and formed on or attached. to the frame C. When the eccentrics are turned forward, thcmag'azines the arms may he placed in position to re out to llolnans, No. 830,436.

' from the magazines into the vertically chanseated in the under side of the throat. cscapemcnt mcchamsm as a whole is hrmly to receive and guide the edges of the matrices I E. Each of the magazines rests upon and is sustained by an underlying support 0 secured to or forming a part of the frame C. The lower or forward ends of these supports c extend upward and engage the front. ol a shoulder on the magazine to prevent the latter from sliding forward. By lifting the torward end of the magazine, it may he disengaged from the retaining shoulder, after which it is free to slide forward and downward out of the machine to he replaced hy another.

In order to sustain the outgoing magazine, I provide on each side of the machine the for wardly and downwardly extending arm M having an upturned forward end adapted to engage projections 1) formed on the edges of the magazine in a manner well known in the art;

The arms M are secured to the slide f which carries the est-.apemcnt bar, so that by moving the slides upward and downward,

ceive and support any one of the outgoing magazines. The action of these arms in sustaining the magazines is essentially the same as that of the arms 1/ shown in the U. 5. Patlhey ditl'er, however, from tl arms of llomans in that they are adjusted vertically so as tocoopcrate with dill'crcnt magazines at dill'crcnt levels. whereas the llomans arms may he operated at one levcl only.

F represents the cscapclncnt mechanism for controlling the delivery of the matriccs nclcd plate or raceway (i. through which they descend to the ordinary wunposing or assembling mechanism. The cscapcment mechanism consists of an inclined channeled throat or guidcfadaptcd to he joined to and to form a continuation of either one of the magazines and of a series ol' cscapcmcnt lcversf, one for each channel ol the magazines. The

connected hy arms f" to vertical slidcs f scatcd in grooves or guides in the main-l frame. This arrangement permits thc cs-, eapcmcnt mechanism, alter the magazines arc rctractcd as in ig. 2. to he raised or lowered hy hand. or hy suitahlc mechanism. I to any required level, so that when the magazines arc again advanced to thc l'orward position shown in Fig. l. the cscapcincnt devices will stand in opcrativc relation to the particular magazine l'rom which matrices arc.j for thc time hcing. required.

Locking pins. latches. or any othcrsuitahlc devices may he used to hold the slides in their ditl'ercnt positions. many such devices 1 heing familiar to thc skilled mechanic.

In Fig. thc cscapcmcnts are shown in operative relation to the lowermost maga-l tar1l "arrested hy the lower lip.

Below each cscapcmcnt is mounted. in the cscapcmcnt l'ramc. a vertical reed or slide). actuated hy the kcyhoard mechanism. as hereinafter descrihcd. and acting at its upper end against the cscapcment lever for the purpose of reversing its position. When thus reversed. the upper lip ol the escapemcnt is withdrawn and the matrix permitted to pass into the throat t. where it is momen- Whcn thc cscapcment is released. it rcsumcs its original position. permitting the lirst matrix to pass out of the throatfand into the raceway G. while at the same time the sccolnl matrix. advancing to thc position vacated by the lirst. is in its turn arrested hy the upper end of thc cscapcmcnt.

\Yhcn matrices are to he delivered from a particular magazine. it is only necessary to move the l ramc and thc contained magazines rearward. after which thc cscapcmcnt mechanism is moved directly upward or downward to a point opposite a selected magazine and the magazines inovcd forward until the one selected joins the cscapcmcnt mechanism. in the manner shown in l ig. I.

it will he ohscrvcd that the matrices delivered from the magazine into the throat are innncdiatcl l'tlt ascd from the lattci. so that under normal conditions. the throat] em )ty and thc matrices are conlincd lioll witllin the magazines proper. ln c nscuencc of this arrangcmcnt. the magazines may be shifted and the cscapcmcnt raised or lowered at any instant. and without lirst releasing or moving any of thc matriccs for the purpose.

lrcparatoiw to the movement of the magazincs. it is ncccssai' to lock thc contained matrices thcrciii. and it is also necessary to lock "them last in those magazincs which are notconnectcd to thc cscapcmcnt devices. I propose to use for this purpose, in connection with each magazine, a locking device of any suitahlc character to engage the matrices. in thc l'orm shown, this locking mechanism consists of a rocking har ll extendedacross thc umlcr side of each magazine near its delivery end,-thc har heing providcdat the upper and lower edges with thc'lips passing through slots in the magazine to engage the cars of the contained matrices. The bar, which rocks about. a horizontal axis, is provided with a torwardly extending arm l1, and is acted upon by a spring It which tends to I ment with the foremost matrix.

For the purpose of imparting motion to the escapement-actuating slides or reeds f when the escapements are at the various levels required, I propose to. provide an adjustable connection of any sort between them and the keyboard mechanism. The arrangementishown in the drawing is as follows I, I, represent a series of reeds or slides vertically guided in the main-frame and connected with a keyboard mechanism of any ordinary character, by which'they will be raised individually as the finger-keys are mani ulated. On the under side of the movable ame C I pivot, in line with the-reeds f 5 and I, angular levers J and also levers K' jointed thereto. Springs L hold these levers normally in the position shown. Each of the reeds f is provided with four notches. f at distances apart equal to that between the magazines, and so located that when the escapement mechanism is set in operative position at either level and the magazine frame then moved forward, the levers K will enter the notches in the reeds f and the levers J at the same time assume an operative relation to the reeds I, as shown in Fig. 1, so that whenever the reed I is lifted throu h the instrumentality of the fin er-key, it wil comthe intermediate levers J and K to the reeds f ,-raising the latter and reversing the positionof the escape inents so that the foremost matrix will pass into the throat f. When the, reeds I are released, the position of theesca ement will be reversed and the matrix will While I have described above, and'have illustrated in the drawings, details of construction which represent my invention in a commercial form, it is to 'beunderstbod that the details may be widely modified within the limits of mechanical skill without passing be yond the scope of the invention, For example, the escapement mechanism may be modified, the. supports for the magazine's may be changed rovided only they permit the magazines col ectively or individually to be moved to and from the escapements,'and' the escapement mechanism may be modified in any mannacsvhich will admit of its bein discharged.
